To all whom it ma concern:

Be it known t at we, Cnanaas J. Bose and JOHN W. Kosamnn, citizens of .the United States, and residents of Syracuse, in'the county of Onondaga and State of New York, have invented certain new and useful Improvements in Type-Writing Machines, ofwhich the following is a specification.

Our present invention relates to paper iding and controlling devices or paper 'ngers, and its general object 15 to provide improved devices of the character specified.

More specifically stated, our improved paper finger contrivances were constructed with a view .to enabling them to be expeditiously and readily removed outof the path of the aper thatis being fedover the platen, this ing particularly advantageous m;connection with manifoldin work since erasures may. be readily eilectc. on the separate sheetsofth' ,manifold pack.

The gist of our" present invention resides in connecting the paper finger proper or paper guide with the device on which it is supported or ca'rried by a pivot or joint, the axis whereofis diagonal to the axis of the platen instead of parallel therewith as in rior constructions. This enables the-paper iingers to engage with the side margins of the paper and to be swung-by a single pivotal movement away from the platen and laterally outside of or beyond the side edges of the paper so that the paper is quickly freed for such manipulation as is desired.

To the above and .other ends, our invention consists in the features of construction, combinations of devices and arrangements of parts hereinafter described and particularly pointed out in the claims. 4

In the accompanying drawings, Figure 1 isafragmentary front elevation of the up per portion of a Monarch front-strike typewriting machine to which the preferred form of the invention is shown as applied. Fig. 2 is a corresponding view showing the paper finger contrivances thrown oil or in inoperative position. Fig. 3 is a vertical sectional view taken transversel of the latcn on a lane indicated by t e dotted ine a:a: in ig. 1. Fi 4 is a fragmentary plan view of the rightand portion oflFig. 1. Fi 5 is a fragmentary end view of the rightand paper finger contrivanoe in its inoperative or Fig. 2 position. Fig. 6 is a perspective view of the carrier portion of one of the paper finger contrivanoes, togethcr' with the pressure'spring for the paper finger "proper. Fig. 7' is a fragmentary end view of a modified construction.

As appears from Figs..1 ,and 3, the top plate 1 of the Monarch machine hasri from it brackets 2 to which aresecn oppositely grooved uide rails 3, said rails cooperating throng anti-friction balls 4' with'the grooved rear-or-slide-bar 5 of the 'platen carrier or carriage, which further comprises forwardly extending end bars 6.

Journaled on said end bars is the side or spindle 7 of a rotary platen 8 with which'is' operativel wheel 9, tiie same being adapted to be actuated and controlled b devices of'ordinary construction not herein shown. "The usual paper feeding or pressure rollers 10 and '11, Fig. 3,-are provided for advancing the paper around the platen and upward at the front side thereof ast a scale or scale .plate'12 that extends engthwise' of the platen paral- 1o. connected a line'spacing'mtchet;

lel with and below the printing line whidr is at the middle of the front face thereof. 1 The paper finger contrivances are mounted on a rod or bar 13 thatis arranged above theplatcn'and somewhat to the rear of the :ver," tical plane passing through the laten a said rod or bar 13 being detachably.

to the and bars 6. Preferably two paper finger contrivances embodying our inven-.

tion are associated with the platenat its 0pposite end portions, these contrivances being proper being off-set inwardlytoward each other and the axes of their pivotsbeing 6ppcsitely disposed. Each paper'fin er contrivance comprises a carrier or brac at that is slidablysupported on the rod 13 and a 90. similar in construction but the paper fingers right-hand carrier is shown detached in Fig. 10%

6 and will be described in detail, it being understo'od that thede'scription applies equally well to the left-hand carrier except that the axis or pivot supported thereon is oppgsitally 106 dispose This carrier, designated reference numeral 14, ispreferabl made of sheet metal and is bent into a shape so that it comprises a. web or connecting portion 15 and two forwardly extendin ears 16 vand 17. 'From'the top of the cal-.1 rises a 11 1,)

lug 18while the forward portion of the ear 17 terminates in an upwardly extending lug 19. The ears 16 and '17 are formed with holes 20 to tit. over the rod 13, and projecting inwardly fronr each hole is a lug or tongue 21 which'oooperates with a groove 22 out in the rod l3 and extending lengthwisethereof at its lower front side. This tongue and groove connection between the carrier.

14 and its support or rod 13.en ables said carrier to be slidalong and adjusted at desired points lengthwise ofthe rod 13 while prerotated on said rod. To hold the,earrier in adjusted positions, friction means arepro vided comprising a spring 23, slightly bowed downward, which is confined between the "venting said carrier from being turned or cars 16 and 17 and is reduced at its ends to' engage in notches 24 in said ears. As will be clearly understood from Figs. 3 and 4 the outer lug 19 of the right-hand'carrier is forward of the inner lug 18, andboth lugs are bent leftwardat an angle tothe' planes of the ears 16,:ind'17, said'planes being parallel and at right angles to the axis7 of the platen as well as to the supporting rod 13. These lugs 18 and 19 are providedwithholes in which is mounted a substantially horizontally disposed axle orpivot pin 25 f or supporting the paper finger contrivance proper,

' rier.

and the axis of said pin is at an angle'to the platen axis and to the rod 13 instead of bemg parallel therewith as in the ordinary 'eonstrnction.

tory results by making the angle betweeii the-- in'25 and-the rod 13 substantially': but of course it is to be understood We have obtained satisfacthat the major portion of-said arm 26 'is at right angles to the rod 13. .Said arm terminates at its forwardend in a curved finger portion 32. Hear its end the arm is provided with an inwardly extending offset 33 to which is suitably secured a'downwardly.

extending paper finger properjor guide. 34, said guide curving downward and forward over the front face ofthe platen across the printing line and overlying the scale plate 12. The guide -.or guiding portion 34 of the paper finger is slotted, as indicated at 35, and the sides of the slot are upturned forming ears 36 which support the axis of. a

small rubber. covered plressureroll 37 of ordinary construction,

above the printing line. The pin or axle 25 of the hinged joint or pivotal connection between the guide proper and its support or bracket is also at an angle to a vertical plane passing longitudinally through the platen and is at an acute angle to avertieal plane passing transversely through the rod or bar 13 and theplatenperpendicularly thereto, the line of the hinged oint being also at an acute angle,-to' a-vertical plane passing 'e pressure roll cooperatingthrough said slot with the papef throughthe guiding'portion of the paper finger and at right angles to the rod 13.

Y As-stated,'the left-hand paper finger contrivanee is oft-substantially the same con that such angle may be varied without departing from theinvention.

The paper finger device proper-comprises struction .as'. is the right-hand contrivanee heretofore described except that the pivot pin 25 isoppositel dis osed andth'e'oli-set 33 projects-inwar to t eright and toward the 'leftwardly, projecting-Holl s 33 of the .-ri hand c ntrivance. The construction is such that e'paper or work sheet, desig-Z nated as p in- Figs l and 2, when it is fed an arm '26 extending-downward and .for-

ward over and in front of theplaten, said rod at its rear being provided with downwardly extending cars 27 which are confinedbetween the lugs 18 and 19 and are in plane's parallel thereto. Said ears areperforated to fit over the pin 25 which serves as an axis about which "the paper finger is adapted to.

turn. The rear end of said rod is also provided with a downward extension 28 that co-' operates with an angular leaf spring 29 comprising a forwardly extending bowed portion or spring tongue that coo crates with theextensicn 28, said spring tin-thee eom. prising a downwardly extending portion that is arranged between the ears 16 and 17 of the carrier and is formed with a slot 30 that fits over :1 lug 31 turned forward and upward from the rear wall or web 15 of said carrier, the spring 29 being thus attaehahly supported on said car- From the pivot 25 the arm 26 extends. horiz ntally forward for a short distanre at right angles to ".aid plri t and then is bent downward and inclined rightward so a at the front of the platen-past the scale p ate 12, is guided by the' guides orfingcrs 3i and pressure rolls37 upward over the frontofthe ,platen, passing between the two arms 26 and the carriers 14, which are adjusted in eonformitynvith the width of the sheet, and over the top .of the rod 13. The

paper fingers (proper'are held in cooperative spring presse relationship withthe platen and the paper-thereon by. reason of the'pres- I sure of the tongue portion ofthe spring 29 acting against the rear end. portion 28 of the arm .26 aelc of the pivot 25. T he,end of this portion 28 is cut off substantially parallel .with the pivot 25, and it is also inclined downward and rearward at an angle to the horizontal plane.

platen, instead of swinging upward in planes at right an les to. the platen axis,

swing-directlvim ia'gonal .planes of rotation andarethus-turned both upward-and laterally'outward away from each other, the

. pivotal exes'being so disposed that this the initialmovement of the paper finger is about a diagonal axis and is outward awa from -ths platen surface and also latera I heoarriers 14 being adjusted sothatthe I side edgesof the paper are normally inside of or between the arms 26, it will-be under etoodthatthe throwing off of the paper fingers entirely frees that portion of the pa-- per which is above or has been advanced past the scale plate 12." This is especially advantugeous if corrections are to be made in manifold work as it enables the outer sheets of paper comprised in the manifold pack, together with the interleaved carbons, to be separately manipulated so that erasures may be made separately on said sheets. Such manipulation is well understood and it is not necessary to go into the details of it. Other advanta of our novel construction will occur to tfiose skilled in the art.

It will be understood that as the pivotally mounted pdrtions or guide fingers of the contrivanocs are swung upward and laterally outward as described, the end portions 28 .will coiiperatc with the spring tongues, deprcsking. "said tongues, and that when the sa dfingcrs havebeen swung past the dead center said tongues will rc-act against the portions 28 and will hold said fingers up in i'noperative position as shown. Thus the springs 29 are double acting, serving both to apply operative pressure to the paper fingers normally and also to hold said fingers in inoperative positions.

Various changes may be made without departing from the principlesof our present invention, and one illustration of such changes is shown in Fig. 7 wherein the bow spring 23 which frietionallv holds the paper finger contrivunce in adjusted position 'on the rod 13 is dispensed with and a single spring 38 is employed for providing friction between the paper linger carrier and its supporting rod, and also for applying pressure to thepapcr finger proper. Said spring engages frietionally with the top of the rod 1? and extends downward behind said rod between the walls of the carrier. pressing against the lower end of the web ortion 15 of said carrier. Forvard of t \0 rod 13 sa d spring is curved up: ward and rearward. providing a tongue which cooperates with the extension 28. The construction is such that the spring re-acts against the rod 13 with sufiicient friction to prevent lateral displacement of the paper of the fingeroontrivance on said rod while the upper endofii'said spring normally holds -thespaperifinger proper down against the platen. -Said spring also holds said finger of! the platen when it has-been swung to inoperative pOSltIOIl, and at thisti'me the spring pressure againstltherod :13 is lessened sorthat adjustments along the rod --may be effected. We prefer, however, the

first described construction employing the twoisprmgs as in practice it has been found difiicult from themanufacturing standpoint,

to provide for thenicety of adjustment which the single ,springconstruction requires.

- Various otherchanges besides those herein specified may be made without departing from ourinventionpand it is of course to be understood that. the invention may be applied to other styles of writing machines besidss the Monarc 1 typewriter herein illus trate What we claim as new and desire to secure by Letters Patent, is g 1.
